Question

3x + x = -40

Explanation:

Step1: Combine like terms

Combine \(3x\) and \(x\) on the left side of the equation. Since \(3x + x=(3 + 1)x = 4x\), the equation becomes \(4x=-40\).

Step2: Solve for \(x\)

Divide both sides of the equation \(4x=-40\) by 4. Using the formula \(\frac{4x}{4}=\frac{-40}{4}\), we get \(x = - 10\).

Answer:

\(x=-10\)
